Why would a dysrhythmia decrease cardiac output?
What will be an ideal response?
A dysrhythmia interrupts the normal contraction sequence of the heart. If the contraction is shortened, the force exerted by the contraction will be less. Less force results in less blood pumped, thereby decreasing the cardiac output.

You are on the scene in the bad part of town for an unresponsive 18-year-old type 1 diabetic patient. His mother states that he is very noncompliant with his diabetes management and goes unresponsive often due to low blood sugar. After performing the primary assessment, you believe that this is the most likely cause of his unresponsiveness. However, after taking a capillary glucose reading you
are surprised to see that the patient's sugar level is normal. How will you now determine the field impression? A) Recognize that the mother was lying to you. The patient is not diabetic and you now must assume that everything she told you is wrong. B) Recognize that the mother is probably trying to protect her son from jail. Tell her that it is critical that she tell you what drugs he actually took. C) Continue patient care by getting a complete SAMPLE history and perform a complete secondary assessment. D) You cannot make a correct diagnosis in the field because you cannot perform all the necessary tests with your limited scope of practice.
